ICU = intensive care unit, GCS = Glasgow Coma Scale, PEA = pulseless electrical activity, ROSC = return of spontaneous circulation, VF = ventricular fibrillation, VT = ventricular tachycardia.
*Some patients may have multiple findings on the same echocardiogram: cardiac standstill, spontaneous echo contrast, and intra-cardiac thrombus.
